David has pears and apricots in a ratio of 24:20. How many pears does he have if he has 5 apricots?

On the double number line below, fill in the given values, then use multiplication or division to find the missing value.

Answers

Answer:

The answer is 6 pears.

The answer is 6 pears.

First turn the ratio into a fraction.
The fraction would be 24/20

Next find the greatest common factor.

You do this by finding the greatest common factor which would be 4.
Four is the GCF because it is the highest number that you can divide both 24 and 20 by.

Since the question is in the order of pears then apricots you divide 24 by 4 to get the number of pears.

Your final answer is 6.

Answer: 84 in

Step-by-step explanation:
The area of a triangle would be 1/2 bh so the first step would be to find the area of the triangle. So, you would need to multiply 6*6 and then divide it by 1/2. Then you would need to find the area of the rectangle, for this you would need to multiply the length times the width which would be 6*11 then you just add both of the areas up. which would be 84.
The answer is 84 in

Step 1: area of rectangle
A = a x b
A = 11 x 6
A = 66 in

Step 2: area of triangle
A = 1/2 x a x b
A = 1/2 x 6 x 6
A = 18 in

Step 3: total area
A = 66 + 18
A = 84 in

Answer:

The answer is 14,800 square yards.

Step-by-step explanation:

Square Area:bh: 145 x 80 = 11600

225-145=80/2= 40 (the base)

Triangle Area: 1/2 (b) (h): 1/2 (40) (80) = 1600

Since there are 2 riangles multiply 1600 by 2 = 3,200

Add 11600 + 3,200 = 14,800

(This is not the same as my last question) Find the value of X

A. 25
B. 7
C.11
D.18

Answers

Answer:
B. 7

Step-by-Step-Explanation:
This is a right angle, a right angle is equal to 90° since it is 1/4 of 360
(360 is all the way around)

Our equation here is;
5x° + 55° = 90°
(we do inverse operation, inverse of addition is subtraction.)
Subtract 55° from both sides, 55 - 55 cancels out (0)
90° - 55° = 35°

Now our equation is;
5x° = 35°
(to find x we need to find out what 1x equals so we divide 35° by 5°)
(35 / 5 = 7)
x = 7

To make sure we plug in it into our original equation (5x° + 55° = 90°)
5(7)° + 55° = 90°
35° + 55° = 90°
(35 + 55 = 90 so this is correct)

x = 7
